Abstract

Various components for artificial candles and other lighting devices are described that can be used to create a realistic flame effect in the devices. The devices include a flame piece or element that extends upwardly from a body of the device. A light source can be disposed with respect to the flame piece such that the flame piece is illuminated. A variety of drive mechanisms could be disposed within the body of the device that can cause movement of the flame piece with respect to the body or housing. The flame piece can be coupled to a body or housing of the device using various components to suspend at least a portion of the flame piece within the body or housing.

Claims

1. An electric lighting device, comprising:

a candle body;

a flame-shaped piece coupled to the candle body such that the flame-shaped piece can move in at least two dimensions;

a light source disposed within the candle body such that light is emitted on the flame-shaped piece;

an agitator configured to cause movement of the flame-shaped piece with respect to the candle body;

wherein the flame-shaped piece comprises a portion having a hollow interior, and wherein a portion of a support member is configured to extend upwardly within the hollow interior of the portion, such that the flame-shaped piece is suspended by the support member and moves about the support member when a force is applied by the agitator; and

wherein the weight of the flame-shaped piece is distributed such that a center of mass of the flame-shaped piece is located below a point where a tip of the support member interacts with the interior of the flame-shaped piece.

2. The device of claim 1, wherein a portion of the flame-shaped piece is clear such that at least some of the support member is viewable through the clear potion of the flame-shaped piece.

3. The device of claim 2, wherein the visible portion of the support member is configured to resemble a wick when viewed through the flame-shaped piece.

11. The device of claim 1, wherein the flame-shaped piece comprises a cone shaped bottom piece that defines the hollow interior.

4. An electric lighting device, comprising:

a candle body;

a flame-shaped piece coupled to the candle body such that the flame-shaped piece can move in at least two dimensions;

a light source disposed within the candle body such that light is emitted on the flame-shaped piece;

an agitator configured to cause movement of the flame-shaped piece with respect to the candle body; and

wherein the flame-shaped piece comprise a flame-shaped top portion and a bottom piece having a hollow interior portion, and wherein the device further comprises a support member configured to extend upwardly into the hollow interior portion, thereby suspending at least a portion of the flame-shaped piece within the candle body, such that the flame-shaped piece is allowed to pivot about the support member.

5. The device of claim 4, wherein the flame-shaped piece is configured to rotate about the support member.

6. The device of claim 4, wherein the agitator comprises a fan disposed beneath the flame-shaped piece, such that air is directed into the hollow interior portion of the bottom piece.

7. The device of claim 4, wherein the agitator comprises an electromagnet disposed about the support member, such that the support member passes through the electromagnet, and wherein the electromagnet is configured to generate a magnetic field.

8. The device of claim 7, wherein the flame-shaped piece comprises at least one magnet, such that interaction of the magnet with the magnetic field causes movement of the flame-shaped piece.

9. The device of claim 4, wherein at least a portion of the flame-shaped piece is clear.

10. The device of claim 4, wherein the bottom piece comprises a cone shape that defines the hollow interior portion.
